more than an inch long, are of the same colour. The leaves 
are from four to six inches long, ovate-lanceolate, flat, pale 
green, with a rich red marginal line, within which, at the 
distance of a quarter of a line, runs a faint intramarginal 
vein; when bruised they have a faint and rather pleasant 
smell; very few transparent dots are visible ; the veins are 
delicate lines, almost at right angles to the midrib, from three- 
fourths to one and a half lines asunder, and running somewhat 
parallel till they lose themselves in the intramarginal vein ; 
they are held together by fine reticulations. The whole ap- 
pearance of the foliage is that of a Calophyllum. The flowers 
are large and white; the cup is obconical, six lines long, and 
as much across the mouth; the lid however is only half that 
diameter and hangs to the edge of the cup on one side, by a 
narrow neck, so that it cannot fall off; this arises from the 
cup continuing to enlarge after the separation of the lid.

Although this plant was introduced many years ago it 
may be as well to mention that it has again been raised from 
New Holland seeds, collected near Swan River, and is in 
many gardens without a name. It forms a low grey bush, 
thinly covered with long white feeble hairs; the leaves are 
narrow oblong, tapering to the base, and extended at the 
point into a spine of variable length. The flowers are pure 
white, with a faint smell of honey, and grow in dense umbels 
shorter than the leaves. In the form and size of the foliage 
this plant seems to be greatly influenced by climate, the 
leaves becoming small and the spine long as the air is hot 
and dry, or long and large, with a short spine, as it is cool 
and damp. Age too has no doubt an effect upon the species 
in this respect. It is a good greenhouse shrub.

Mr. Rogers received the roots of this Scitamineous plant 
from Northern India two or three years ago ; they were mixed 
with those of Orchidaceous plants. He finds it flower and 
flourish very well in the greenhouse, during the summer,
